    Thank you for the information.
    I found a wire cut between 4 and 9.
    Now it looks like he wants to start but it turns and stops immediately and if I accelerate he misses and ends up choking.

    Starting then immediately stalling is a classic symptom of an EMM needing repair. Do you have about 20VDC cranking, and does it briefly jump up to about 45V for a moment?

    Hello everyone.
    I haven't had too much time since my last message.
    So I got back to it today by trying to take the voltage from the injectors and when I run the starter I am at 0.3v with all the injectors connected. Will this confirm that the EMM is faulty?
    Thank you

    Possibly. I'd suggest you check the AC voltage output of each stator section. An open stator section(s) or magnet separation from the flywheel could be other causes.

    How should I proceed to carry out checks?
    Thank you

    One thing I'm sure is the magnetic flywheel is ok

    Thank you

    1. Disconnect the small plug from the EMM, which is the stator wiring harness.

    2. Identify the pins for each section of the stator, from the link I gave you post #3.

    3. Similar to measuring continuity of each stator section, as you have already performed, connect an AC voltmeter across each section, one at a time.

    4. While cranking the engine, measure the AC voltage of each section.

    5. Compare these measurements to the specifications, which are in the link I included with post #3.

    Links are embedded in green colored text.

    Hello everyone.
    After an accident I could not get back on the controls of my jet. Now things are better at work.
    So I check the AC voltage coming out of the stator.
    So between:
    1et12 6.8v
    2et11 6.8v
    3et10 4.2v
    4 and 9 4.2v
    5 and 8 4.2v.
    When do you think ?

    The stator and flywheel magnets are OK.

    Check the DC voltage on the white/red wire (21/45 vdc power supply), as HiPeRcO suggested in post #12. The white/red wire feeds power to each of the injectors. It also appears in the 4-pin diagnostic connector, near the EMM. You must make this measurement with everything connected. So you'll need to "back probe" a connector by inserting a small probe, such as unwound paperclip, between the wire jacket and sealing boot. Inserting it until it makes contact with the terminal.

    You should measure 21 vdc while cranking and it will jump to 45 vdc once it starts.
